Show HN: MephistoMail – RAM-only ephemeral email with client-side privacy tools

https://www.mephistomail.site/
3•benmxrt•5h ago
Hi HN,

I’m building MephistoMail, a privacy-focused disposable email service designed to decouple digital identity from online services. After seeing how many "temp mail" providers log IP addresses or sell metadata, I wanted to build something that prioritizes total digital hygiene.

New Key Features:

Volatile Memory Storage: We use a RAM-only infrastructure. No incoming messages or session data are ever written to a physical HDD. Once the session terminates, the data is cryptographically wiped.

Client-Side Password Generator: Integrated entropy-based generator that runs locally in your browser. Create high-security passwords for your registrations without them ever touching our servers.

Secure QR Handoff: Transfer your active "burner" session from desktop to mobile instantly via an encrypted QR link. No need to type complex random addresses on your phone.

Multi-Account Tunneling: Manage multiple anonymous identities simultaneously through a unified interface.

Custom Alias Creation: Define your own usernames on our secure domains for more professional-looking temporary identities.

The Stack:

Frontend: React, Tailwind CSS, Lucide icons.

Backend Logic: Powered by Mail.tm's stable API for zero-latency delivery.

Privacy: Strict No-Logs policy, TLS 1.3 encryption, and no tracking cookies.

I’m looking for technical feedback on the UX and the "Persona" tool integration.

Happy to answer any questions about the implementation!
